I suspect this is via REE. Can anyone confirm this?

6125 Noblejas - yes CRI English sce at 2100-2257 UT is relayed via
Noblejas Spain relay site. Totally overmodulated signal from a distorted
transponder audio channel. Signal a fifth second ahead of all other CRI En
channels, like Cerrik-ALB 5960, 7285; Kashi-CHN 7190, 9600 kHz.
Listen to the attached MP3 file. From about 2057:40 UT the usual REE
interval signal noted, for about 2min15sec, then some three time pips from
Madrid bc house followed, then switched over to the totally distorted
overmodulated CRI signal, after 2min20secs at 2100 UT.
7215 Samara - a similar distorted CRI signal from the "?very same
transponder satellite?", noted at around 2030 UT, in French language of
course. Samara tx starts with open carrier just after 2000 UT and
continues open carrier til 20.24:45 UT, when local Samara pips procedure
starts, 6 seconds pip, 6 seconds pause for about 2 minutes. 2030 UT CRI
starts on very overmodulated level, see enclosed MP3 file attachment.
French program is ahead, - of 7200 Urumchi-CHN 2 sec behind, of 7350
Kashi-CHN site - 1/5th second behind.
(later) ... and also the 2.5 minutes on 6125 kHz sounds excellent, when
INTERVAL SIGNAL audio did originate from REE control room, it was a superb
quality. The Noblejas transmitter unit is 100% in order.

Checked the discussed 6125 transmission: Carrier on at 2058, audio on some
seconds after 2100 into announcement in progress. Huge level, indicating a
single-hop signal. Audio indeed horribly distorted and absolutely
unlistenable, but there are no signs of the transmitter being actually
overmodulated, instead it seems that they grossly overdrive the audio way
back in the feed chain. No signal could be detected on 6125 before this
big carrier came on. Noblejas indeed appears to be a good bet.

7170 kHz - Also CRI via Moscow [Taldom] site in English at 2200 UT uses
that distorted satellite transponder. But receiver equipment seems
different, let's say a little bit better or wider dish, but STILL far too
small audio filter like phone line limit.
(Bueschel, ibid.)
It's probably another circuit of the same system, hence a little bit less
distortion. But it could also be that it's just less obvious there because
not so much audio processing than at Noblejas is in use. I think it was
Robert Orban, the inventor of the Optimod product line, himself who put it
frankly: "Garbage in, more garbage out."
And yes, the audio bandwidth is obviously limited to phone standards, like
300...3400 Hz. This is apparently the cheapest kind of audio circuit one
could get in the old days. Rather common were also 7 kHz bandwidth for AM
transmission (I heard somewhere that the old audio circuits to the Soviet
shortwave sites were specified as 50...6300 Hz) and of course 15 kHz for
FM transmission and studio connectivity.
Btw, I forgot to note that of course 7275 sounds excellent, just as
always.
And please make my note on CRI via Switzerland, gone in 1998, eight years
ago, rather than nine. It's still almost a shock to realize that this was
in fact eight years ago, almost a decade . . . DXLD not yg
Just checked the situation at 2200: 6125 continued beyond 2200 without any
break. 7170 had open carrier and joined the same CRI feed at 2200. Same
